Delaware County's 2026 budget raised the county property-tax levy by roughly 19%, and the bill that arrived back in February now has a near-term due date. According to WHYY's reporting on the increase, the average county homeowner, on a home assessed around $255,000, is paying on the order of $188 more per year, or about $16 a month, under the new rate.
Per the Delaware County Treasurer's current-year schedule, county real-estate bills were mailed in early February, the 2% early-payment discount period closed around the start of April, and the face (at-par) amount is due by June 1, after which the bill moves into its penalty period.
A correction: a county tax bill is not "newly hitting mailboxes" in late May. Vol. I, No. 10 reported the increase and its effect on residents. The mailing happened in February, and the operative date now is the June 1 payment deadline.
